What is a word?

It has been estimated that average speakers of a language know from 45,000 to 60,000 words. This means that we as speakers must have stored these words somewhere in our heads, our so-called mental lexicon. But what exactly is it that we have stored? What do we mean when we speak of ‘words’? In non-technical every-day talk, we speak about ‘words’ without ever thinking that this could be a problematic notion. In this section we will see that, perhaps contra our first intuitive feeling, the ‘word’ as a linguistic unit deserves some attention, because it is not as straightforward as one might expect.

If you had to define what a word is, you might first think of the word as a unit in the writing system, the so-called orthographic word. You could say, for example, that a word is an uninterrupted string of letters which is preceded by a blank space and followed either by a blank space or a punctuation mark. At first sight, this looks like a good definition that can be easily applied. So now, you can download this e-book, it gives you all things you need
